PATRICK CASSIDY, OF NEYV YORK, N. Y., ASSIGNOR OF ONE-HALF TO I.

OF SAME PL ACE.

PRIVY-SlNK.

SPECIFICATION forming part of Letters Patent 1%. 331,632, dated December 1. 1885.

Application filed April 18, 1885.

To a-ZZ whom it may concern:

Be it known that I, PATRICK Cxssrnv, a citizen of the United States, residingin the city of New York, county and State of New York,

have invented a new and useful Improvement in PrivySinks, of which the following is a specification, reference beinghad to the accompanying drawings, in which- Figure l is aside View. Fig. 2 is a longiro iigudinal section, and Fig. 3 is a transverse sec- A is the lower portion of the sink. Bis the upper portion of the sink, inclined inwardly.

C is the plug, fitting into the outlet D. a and 1 b are flanges.

Similar letters of reference indicate corresponding parts throughout the several views.

My invent-ion relates to the construction of privy-sinks adapted to the use of city schools,

public buildings, tenement-houses, factories,

and other buildings where, from the number and character of the occupants, the use of water-closets as usually put in dwelling-houses is rendered very undesirable, and yet where the use of the old-fashioned privy-vaultin the rear yard is no longer allowed by the health laws now in force in mostof the larger cities.

Gornparatively shallow sinks of cast iron.

forming the bottom of a privy-vault,liave been frequently used 'in the past. lhe vertical brick-work built from the sink upward permits water and foul matter to percolate through and saturate the ground or surrounding filling,

and this vertical line of wall catches much soil 5 as it drops from the users of the privy, thus polluting the air and altogether forming a kind of construction very detrimental to public health.

My improvement consists in making the 0 portion above the sink proper to incline inwardly, so as to avoid the soil dropping or lodging on the sides of the privy, I make the lower portion, (the sink, A,) of proper width and shape, and having a proper outlet, D, and

fitted with a suitable overflow-plug, G. The

sink A is provided with a surrounding flange,

(6. Above the sink A, I place the inwardlyinclined extension B, which in the accompa- Serial No. 162,648. (No model.)

nying drawings is represented of cast metal, and provided with a surrounding flange, b, so that the extension or upper portion can be bolted to the lower portion, making a Watertight jointwith the help of putty, or in other ways well known to plumbers and workers in iron. The length of these privysinks will vary according to the number of persons they are intended to accommodate at one time. The extension or upper portion may therefore bein one entire casting for the shorter lengths, or may be made up in a number of pieces properly put together for the longer lengths. \Vhile I prefer to make the inwardly-inclined sides, as described, or cast-iron. on account of economy and durability, such sides may be made of other metals or of slate, stone, burned clay, or any other suitable material.

The privy-sink A is placed a suitable distance down into the ground, with the inward ly-inelincd extension B connected together, and above this latter portion is arranged the usual wooden seats. A suitable amount of water is let into the sink, and daily or oftener the soil is let oif by raising the plug. The upper portion, B, from its inclined lines will not only be free from liability to catch. the dropping soil, but its smooth hard surface can be readily cleaned with a broom in case any filth is lodged upon or thrown against it.

The entire construction will be watertight, so that all saturation of the surrounding earth will be prevented. 'ihelodgment ofsoil above the water-line will be avoided, and therefore merits approval from a sanitary standpoint.

NVhat I claim, and desire to secure by Letters Patent of the United States, is

A privy-sink divided horizontally at or near its center into an upper and lower portion, flanged and bolted together, forming a watertight trough having its contracted upper side open for its entire length, substantially as shown, and for the purpose specified.

PATRICK CASSIDY.
